Abstract: The present disclosure discloses a method for creating a distributed management monitoring system to create a distributed management monitoring system based on a distributed file system. Moreover, the present disclosure further discloses a monitoring method of the distributed management monitoring system, the method includes: updating a file of recording monitoring information regularly and correspondingly updating a device descriptor table by a sub-file system of the distributed management monitoring system; updating the device descriptor table and informing a server to update a file descriptor table by the sub-file system; and finding a device descriptor table corresponding to a designated network element through traversing the file descriptor table and reading a designated file according to the device descriptor table by the server. Accordingly, the present disclosure provides a distributed management monitoring system, the system includes: a server, a file descriptor table and a sub-file system.
